Al-Banna, the son of an architect, was born in Marrakesh in 1256[G. Sarton: Introduction to the History of Science; The Carnegie Institution; Washington; 1927; vol 2; p. 998.] .Having learned basic mathematical and geometrical skills he proceeded to translate Euclid's Elements into Arabic][G. Sarton: Introduction to the History of Science; The Carnegie Institution; Washington; 1927; vol 2; p. 998.] .]Works
Al-Banna wrote between 51 to 74 treatises, encompassing such varied topics as Algebra, Astronomy, Linguistics, Rhetoric, and Logic. One of his works, called "Talkhis amal al-hisab (Arabic, تلخيص عمل الحساب ) (Summary of arithmetical operations)", includes topics such as fractions, sums of squares and cubes etc. Another, called "Tanbih al-Albab" [A Djebbar: Mathematics in medieval Maghreb; AMUCHMA-Newsletter 15; Universidade Pedagógico (UP), Maputo (Mozambique), 15.9.1995.] , covers topics related to:
*calculations regarding the drop in irrigation canal levels,
*arithmetical explanation of the Muslim laws of inheritance
*determination of the hour of the Asr prayer,
*explanation of frauds linked to instruments of measurement,
*enumeration of delayed prayers which have to be said in a precise order,and
*calculation of legal tax in the case of a delayed payment
Yet another work by al-Banna was "Raf al-Hijab (Lifting the Veil)" which included topics such as computing square roots of a number and theory of continued fractions.[G. Sarton: Introduction to the History of Science; The Carnegie Institution; Washington; 1927; vol 2; p. 998.] This work was also the first mathematical work since Brahmagupta to use an algebraic notation, which was then further developed by his successor Abū al-Hasan ibn Alī al-Qalasādī two centuries later.
